OLE C. SYVERTSEN, OF TAUNTON, MASSACHUSETTS, ASSIGNOR TO WEIR STOVECOMPANY, OF TAUNTON, MASSACHUSETTS, A CORPORATION 0F MASSA- CHUSETTS.

To all 'whom fit may concern Be it known that I, OLE C. Srvnirrsing, ofTaunton, iii the county of Bristol and State of Massachusetts, a citizenof the United States,;have invented new and usevful Improvements inGras-Stoves7 ot which the following is a specification.

My invention relates to improvements in gas stoves, and especially to astove having a burner chamber or one thatcan be .used for broilin'g, andan independent bake chaniy tarded circulation of hotar will be etl'ectedthroughout'the `chambers of tliestove and passages connecting therewiththat .air dihigh degree of temperature; vto provide also for apreliminary heating of theaii" directed intothe burnerchamber and toprovide also for 4the retention of heat'in both chambers by meansof` acirculation ofv hot air throughout the walls surrcundin and forming there? spective chambers or y the retention of hot air therein acting as aninsulating means for the conservation of heat within the respectivechambers. My invention can bestbe seen and understood by reference tothedrawings,in-

which Figure 1 shows the stove partly in front elevation b ut mainly insection. Fig. 2 is a cross vertical-section of the stove.

Referringv to 'the drawings :-1 represents the stovehavingt'ormed.therein the respective chambers 2 and 3. Of t-hesetliebottom chamber 2 will hereinafter be lreferred to as the burner chamberinasmuch vas it contains a burner 4; and is used for broiling. ''llieupper chamber 3 isthe bake chamber 0r The respective chambers areseparated from one another bya partition or plate 5 connecting with thewalls of the stove formiiigthe chambers; while access is lia-:l

to the saine 'from the front of the 'stove through doors 7 and 8respectively, the door 7 closing the burnei' chamber, the door 8 theoven. l

especiallyp'ertains to the'walls ot' the stove t'orniing the respectivechambers for it iS by and through these walls that I am en abled tovattain the objects of my linvention above referred to. l

Referring accordingly to Fig. 1 it will be -seen that the side walls ofthe stove forming the sidesot' the respective chambers-consists otseparate spaced plates t), 10, 11, re

speetively. Of these plates the plates 9 andj 10 form vclews at thesides of thestove extending alongside the respectivo oven and burnerchambers therein. The plates 10'and 11 it'orni compartments forcontaiiiingdead air. Interposed between the plates 9 and 10 arepartitions 12.1 These partitions are lo-` cated vsome little distancebelow the plane plane of the bottom ot the burnerchamber.

The partitions-l2 act to divide or sepa atc the space between therespective plates 9 and '10.into separate air containing andY ilue`forming compartments 13 and lll, respecyce . of the oven and preferablynot :tar above the` tively.V Ot' these compartments the ones 13 extend`alongside the burner chamber cn 1cit-her side therco't in the part`lying below the partition 12 and at the bottom or lower end 15 thereofare open to the atmosphere.V

The compartments 13 also connect'with the burner chamber b wa of oieniuos 1(3.ii1 :D

the inner plates 9. The compartments 141 extend alongside both ot' therespect-ive chambers, extending alongside the burner chamber only in thepart lying above the partitions 12. The compartments 111 connect withthe-respective chambersof the Vstove byway of openings 17 and 18 in theinner plates 9L Ol these openings the openings 17 are in theuppcnportion oi the burner chamber and through which openingsron'imunication is had from the upper part of the burner chamber intothe respec- Vtive compartmeiits 14. The openings 18 are in that portionollhc plate J adjacent to the oven by which communication is had fromthe compartments 14. into the oven.

The wal] forming the back ol the stove consists of separate spacedplates 1l) and `20 respectively. These plates are spaced to provide airspaces at the real-ot the respective chambers oli the stove. At a pointadjacent to the burner chamber the plates are pro vided with aninterposed partition 21 forming with the respective plates and theiredge connectionsan' air containing and flue forming compartment 22. At ap oint near the lower endA thereof the outer plate 20 is providedwithopenings 23aifording communi- -cation from the outer air into thecompartment 22. The said compartment 'hasalso conmunication with' theburner chamber through `openings 24-in the inner plate 119.

i These openings 24 are preferably located at chamber.

a point just below the partition'21 and affordfa communicationbetweenthe compartment:22wandtheupper portionof the burner The-wall of thestove forming the top of the oven chamber consists of the separatespaced plates 25 `and 2G, respectively, which have vclosed connectionwi'thjone another' around their respective edges by properly. interposedparts forming a portion of the body ofthe stove and'providing an interyposed air containing'and flue forming compartment'27. lAt the, front ofthe stove the plate 25 is provided with openings 2.8 by

-which communication isihadfrom the oven edges to'form aircontainingcompartments Of these doors -the doors 7 chamber into the compartment27. .At the.

rear of the flue -forming compartment 27 the stoveisprovided with anoutlet passage 29 affordingy an outlet fromthe compartment 27 'to vtheatmosphere. The doors 7 and 8 located at the front of the stove andclosing the respective chambers'therein are also each preferablylprovided with separate spaced plates closed around their respectivebetween them; closing tlle burner chamber consist of the plates 30 and3l, respectively, forming 4an air containing and flue formingcompartment 32 between' them, The plate 3l along the bottom edge thereofis provided with` chamber.

The door 8 which closes the oven or bake 'chamber lprovided `withseparate spaced plates 35 and 3G closed around their respec# tive edgesto form an air containing compartment 37 between them. The bottom ofthestorc or wall forming the bottom of the 7. burner chamber consists ofa plate 38.

" p In tlieopeiation of the stove air will enter at the sides of thestove through the openings 15 at the bottom thereof, thence pass throughthe compartments 13 and openings 16 into the bui-ner. chamber. At theback of the stove air will enter at the point of openings 23 into thecompartment ,22 and thence .pass i-nto the burner chamber throughopenings 241. At the front ofthe stove air will enter the compartment`forme'din the `door 7 by way of the opening v3.3 at the bottom,l

thence pass upwardly through Vthe compartment 82 and enter the burnerchamber through openings 34e.,v The air thus freely delivered to the.burner chamber becomes vhighly heated therein and passes out of thischamber through openings'v17 at the sides of the stove, thence proceedsupwardly through therespective compartments 14 and enters the oventhrough openings 18g The heated air p-asses out of the oven by way ofthe openings 2S atth'e toplthereof and into ,the compartmentfor flue 27and thence proceeds through this-.compartment over the` top of the oven.chamber to the outlet passage 29 Aat the back of. the stove. 4

It willv beseenalso that both the oven andburner chambers are surroundedeither by air containing compartments through "which heated air isflowing, or in which heated air is retained, thus acting to retain 'othe heat invboth` chambers and especiallyv that forming the oven.
